SQL Server 2016 offers a new tool for performance tuning called Query Store. This holds metrics that let you quickly see when an execution plan change has negatively impacted the database.
A database query times out and you don’t know why. The estimated query plan is revealing the problem, so you remove the timeout entirely. An hour later it is still running and you are no closer to getting the actual execution plan. If only there was a way to find out what is actually happening inside the server. With Live Query Statistics in SQL Server 2016 you can now answer that question.
Data masking is a necessary, but error prone process. You only need to forget the mask one time to leak sensitive data. SQL Server 2016 attempts to address this with a feature called Dynamic Data Masking.

If you want to apply security rules on a row-by-row basis, you have to simulate it using stored procedures or table value functions, and then find a way to make sure there is no way to bypass them. With SQL Server 2016, that is no longer a problem.
